2. Early Life and Education

• 2-1. Birth and Early Education in Croatia

• Nikola Tesla was born on July 9, 1856, in Smiljan, a village in rural Croatia, which was then part of the Austro-Hungarian Empire. His father was an Orthodox priest, and his mother, although uneducated, was highly intelligent. Tesla was the second son in a family of two boys and three girls. His older brother, Dane, died in an accident when Nikola was five years old. Tesla demonstrated remarkable imagination and creativity from a young age and became fluent in six languages. He attended school in Gospic, graduating as a brilliant student who had taught himself as much outside the classroom as he had learned inside.

• 2-2. Immigration to the United States

• In 1884, Nikola Tesla immigrated to the United States. He arrived in New York with just four cents in his pocket, a few of his own poems, and calculations for a flying machine. He initially worked under Thomas Edison but soon resigned due to their differing methods and professional disagreements. Tesla's engineering reputation grew, and he found financial backing to develop his alternating current (AC) generators and motors, leading to the establishment of the Tesla Electric Company in 1887.

• 2-3. Initial Collaboration with Thomas Edison

• Upon arriving in the United States, Tesla started working with Thomas Edison. This collaboration was short-lived due to their opposing scientific perspectives—Edison was focused on direct current (DC) systems, while Tesla's innovations were primarily centered around alternating current (AC). Despite their differences, Tesla's work continued to gain recognition, paving the way for significant advancements and eventual rivalry between the two prominent inventors.

3. Collaboration with George Westinghouse

• 3-1. Partnership and key patent sales

• In May 1888, Nikola Tesla entered into a significant partnership with George Westinghouse, the head of the Westinghouse Electric Company. Westinghouse purchased the patent rights to Tesla's polyphase system of alternating-current (AC) dynamos, transformers, and motors. This transaction marked a pivotal moment in the history of electricity as it precipitated a major power struggle between the direct-current (DC) systems championed by Thomas Edison and the AC systems promoted by Tesla and Westinghouse. The partnership between Tesla and Westinghouse was fundamental in advancing the adoption and implementation of AC technology over the existing DC systems.

• 3-2. Promotion of AC systems over DC

• The collaboration with George Westinghouse allowed Tesla to continue his innovative work on AC systems. Westinghouse utilized Tesla's AC system to light the World's Columbian Exposition in Chicago in 1893. This public demonstration showcased the superiority and potential of alternating current over the direct-current systems proposed by Edison. The success of this demonstration played a crucial role in Westinghouse and Tesla winning the contract for the first power machinery installation at Niagara Falls, which later provided electricity to Buffalo by 1896. The widespread acceptance and implementation of Tesla's AC technology under Westinghouse's support marked a significant victory in the war of currents and established AC systems as the standard for electrical power transmission.

4. Major Inventions and Innovations

• 4-1. Alternating Current (AC) motor and system

• Nikola Tesla conceived the idea of the Alternating Current (AC) motor during his time at the Polytechnic Institute in Graz and University of Prague. He developed the rotating magnetic field principle which became the basis of alternating-current (AC) machinery. In 1888, he sold the patent rights for his AC dynamos, transformers, and motors to George Westinghouse. This development led to a significant power struggle with Thomas Edison's direct-current (DC) systems, with Tesla's AC approach eventually triumphing.

• 4-2. The Tesla coil

• In 1891, Tesla invented the Tesla coil, an induction coil widely utilized in radio and television sets as well as other electronic devices. This invention was crucial for his later experiments with electrical resonance and wireless communication. The Tesla coil became a standard component in the generation of high-voltage, low-current, high-frequency alternating-current electricity.

• 4-3. Advancements in electrical resonance and wireless communication

• Tesla's countless experiments included work on electrical resonance and various types of lighting. To demonstrate the safety and potential of AC power, he conducted public demonstrations where he lit lamps by allowing electricity to flow through his body. His experiments in electrical resonance eventually led to the development of technologies used in radio broadcasting. Additionally, in Colorado Springs, Tesla discovered terrestrial stationary waves and conducted wireless transmission experiments that included lighting lamps wirelessly over distances up to 25 miles.

• 4-4. Remote-controlled boat

• In 1898, Tesla invented and demonstrated a teleautomatic boat guided by remote control. This invention combined wireless telegraphy with robotics and showcased Tesla's forward-thinking application of remote control technology. Despite initial skepticism, Tesla's claims were proven in front of a crowd in Madison Square Garden, further establishing his reputation as an innovative force in wireless technology.

• 4-5. Discovery of terrestrial stationary waves

• During his time in Colorado Springs, from 1899 to 1900, Tesla made what he regarded as his most important discovery: terrestrial stationary waves. Through this discovery, Tesla demonstrated that the Earth could be used as a conductor and made to resonate at certain electrical frequencies. His experiments included creating artificial lightning and wireless power transmission, which illustrated the potential for wireless electrical distribution on a global scale.

5. Challenge and Rivalry: The War of Currents

• 5-1. The clash between Tesla and Thomas Edison

• The rivalry between Nikola Tesla and Thomas Edison is one of the most iconic in the history of science and technology. Both men were brilliant inventors, but their approaches to technology and invention were starkly different. Tesla, who was known for his extraordinary memory and ability to visualize intricate designs without preliminary drawings, worked predominantly on his own. Edison, on the other hand, functioned with a collection of assistants and held significantly more patents. Their feud, known as the 'War of Currents,' centered around Tesla's promotion of alternating current (AC) and Edison's support for direct current (DC). This clash was not merely a battle between two inventors but was also a significant turning point in the adoption of electrical systems worldwide.

• 5-2. Advocacy for AC versus DC

• The 'War of Currents' saw Nikola Tesla advocating for the use of alternating current (AC) while Thomas Edison championed direct current (DC). AC, promoted by Tesla, was more efficient for transmitting electricity over long distances and eventually became the dominant system worldwide. Edison, however, persisted in promoting DC, which he deemed simpler and safer, although it was less efficient over long distances. Edison even resorted to public demonstrations to discredit AC, including the electrocution of animals to show its potential dangers. Despite these efforts, Tesla's AC system ultimately proved to be more viable, leading to its widespread adoption.

• 5-3. Impact of the hydroelectric plant at Niagara Falls

• One of the most significant victories in the 'War of Currents' was the establishment of the hydroelectric power plant at Niagara Falls. Nikola Tesla's AC system was chosen to harness the energy of the falls, marking a monumental step in the adoption of alternating current. The plant was the first of its kind and demonstrated the practical viability and superior efficiency of AC in powering extensive areas. This success not only underscored Tesla's technological prowess but also solidified AC as the standard for electrical transmission, ultimately shaping the future of global electrical supply.
